Geothermal maps - WCS services

Map represents the calculated (surface) heat-flow density (HFD) in mW/m2 with topographic correction. It is made with data from 119 boreholes from the measured temperatures in the available boreholes and measured thermal conductivity on cored rock samples from the same boreholes. The pattern of the HFD isolines is affected by numerous parameters, particularly the thermal conductivity of rocks, rock permeability and fracturing, fluid content of the rocks, and all are reflected in the measured temperature gradient in the boreholes.本热流密度分布图展示了经地形校正的计算所得地表热流密度（heat-flow density, HFD），单位为毫瓦每平方米（mW/m²）。该分布图依托119口钻孔的实测数据构建而成，数据涵盖现有钻孔内的温度实测值，以及取自同批次钻孔的岩芯样本的热导率实测结果。热流密度等值线的分布格局受诸多参数影响，其中尤以岩石热导率、岩石渗透性与裂隙发育程度、岩石含流体性最为显著；上述所有因素均可通过钻孔内测得的温度梯度得到反映。
